  * any more.
+ *
+ * We _could_ try to update the page reference, but that
+ * doesn't seem to really be worth it either. If we did,
+ * it would look something like this:
+ *
+ *	#define buffer_page(bh)		(mem_map + MAP_NR((bh)->b_data))
+ *	#define touch_buffer(bh)	set_bit(PG_referenced, &buffer_page(bh)->flags)
